RESUMEN
BACKGROUND: During the SARS-CoV-2 global pandemic, one of the longest lockdowns worldwide occurred in Ontario, Canada, during the first wave. For parents and children managing care at home and at risk for COVID-19, the impact on their psychosocial functioning is unknown. METHODS: A total of 122 families of children aged 2-18 years were enrolled as part of the prospective cohort of childhood nephrotic syndrome and completed a survey during the first wave of the pandemic (August 21-December 10), 2020. In a subset, 107 families had data available pre-pandemic to assess change. Validated measures included the McMaster Family Assessment Device (FAD) for parents and children ≥ 12 years for family functioning, the Patient Health Questionnaire for Depression and Anxiety (PHQ-4) for both parent and child, and Pediatric Quality of Life Inventory (PEDSQL™-V4) for children only. Scores were compared using Student's t-test or the Mann-Whitney U test, as appropriate. RESULTS: Among the 107 children, 71% were male with a mean age of 9 years old at the time of questionnaire completion, and the mean age of parents was 41 years old. Parents and children reported that family functioning improved during COVID (parent: p < 0.01; child: p = 0.05). Children's overall HRQOL declined (p = 0.04), specifically increased sleep disruption (p = 0.01). Increasing child age was associated with a greater sleep disruption (ß = - 1.6 [IQR: - 2.6, - 0.67]) and a related decrease in QOL (ß = - 1.0 [IQR: - 1.7, - 0.2]), adjusted for sex. CONCLUSIONS: Despite the positive effects of family dynamics during the first wave, there were negative effects of sleep disruptions and reduced quality of life in children, especially among older children.
